The first single I ever bought for my first real girlfriend was Showaddywaddy's Three Steps to Heaven!
Showaddywaddy were a kind of teddy boy revival act from the 70's, not particularly good but very popular. There were about eight of them all with different colour teddy boy jackets, brothel creepers (their shoes) and each donning a quiff!
During the mid- 80s they were confined to playing cheesy nightclubs that served scampi & chips in a basket as part of the admission price. I once saw them supporting dance act Hot Gossip!
All that remains to say is Shani Bishop (as you were then), I hope you are well!
